COOLING-CONDENSER FOR GASES.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed July 13, 1910. Serial No. 571,789.

To all whom it may concern:

Be it known that we, VVILLIAM P. NooNAN, a resident of Jersey City, in the county of Hudson and State of New Jersey, and MICHAEL JAMES ROCHE, a resident of VVeehawken, in the county of Hudson and State of New Jersey, both citizens of the United States, have lnvented a new and Improved.

Cooling-Condenser for Gases, of which the following is a full, clear, and exact descripsame areadmitted to Among the principal objects which the the accompanying drawings, in which like parts in all the views,

characters of reference denote corresponding and in which Figure 1 is a perspective view of a condenser constructed and arranged in accord ance with the present invention; Fig. 2 is a vertical longitudinal section of the same, on an enlarged scale, and broken in the center to contract the drawing; and Fig. 3 is a face view of the distributing head employed in conjunction with the present invention.

In its present disclosure the invention is employed as a muffler for internal combustion engines, and in that connection is shown as being connected with the exhaust pipe 8 of an engine of the type specified. The pipe 8 is connected with a nipple 9, which is extended from a distributing chamber to which the said pipe is connected by means of a union 11. The distributing chamber 10 is provided with a series of perforations 12, 12, arranged substantiall as shown in Fig. 3 of the drawings, the 0 cc of which is to provide for the delivery throughout the full circumference of the said distributing chamber of the products of combustion received from the pipe 8. are formed in a raised annular flange 13. The annular flange is extended into the opening between the annularly corrugated metal tubes 14 and 15.

The perforations 12, 12'

The tubes 14 and 15 are dispose-d substantially as shown in Fig. 2 of the drawings, being held in mutual relation by rivets 1Q, 16 and thimbles 17, 17 surrounding the said rivets. The passage 18 thus formed between the tubes 141 and 15 may be contracted or expanded as desired.

The distributing chamber 10 is formed from cast metal, and the chamber is of any suitable dimension, being formed to provide for an easy outlet of the gases from the exhaust pipe 8 into the said chamber, where they are expanded. A similar chamber 19 is mounted at the opposite or delivery end of the said tubes 14 and 15, being secured thereto in a similar manner, and having an annular flange pierced by the perforations 12, 12 as shown in F ig. 3 with reference to the flange 13 of the distributing chamber 10. The chamber 19 is secured to the tubes 14 and 15 in the same manner as is the chamber 10. a series of valve controlled outlets 20', 20. The openings through the outlets 20, 20 are controlled by valves 21, 21, said valves being adapted to limit or determine the flow throughthe said outlets.

It will be noted that a clear passage is provided for the air through the center of the passage 18 and the chambers 10 and 19.

If desiredthe condenser may be provided with a tubular covering, not shown in the accompanying drawings, to confine and hold the air in passing contact with the outer projections of the tube 1 1. In both instances it will be noticed that the radial extensions of the corrugations forming the passage 18 are swept by the cooling air more readily than are the interspaces formed by the inward projections of the corrugations. The result of this action is to provide at the outward and inward extension of each of the convolutions of the passage 18 a condensing surface. It will also be noticed that by reason of the variation in thediameters between the inwardly extended. and the outwardly extended convolutions, a rapidly alternated condensation and expansion is effected in the products of combustion or heated gases passingthrough the said passage 18. The purpose of this construction is by this means effected, to wit, that prior to the products of combustion or gases being delivered to the chamber 19, the condensation thereof has been such The said chamber 19 is provided with as to pass without force or explosion into the said chamber, and from thence by way of the outlets 20, 20, without combustion or other disturbance.

While we have herein shown and described our invention as applied to internal combustion engines, we wish it understood that the condenser may be employed in any other use to which it is adapted.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. A condenser for gases, comprising a plurality of concentrically arranged tubes, said tubes being annularly corrugated, and the corrugations of one tube extending between the corrugations of the other tube; means for separating the said tubes to form an uninterrupted evenly spaced tortuous passage extended lengthwise between the said tubes; and an inlet distributing chamber connected with said tubes, said chamber being provided with a series of perforations opening into said passage for controlling the delivery of gas thereto.

2. A condenser for gases, comprising a plurality of concentrically arranged tubes, said tubes being annularly corrugated, and the corrugations of one tube extending between the corrugations of the other tube; means for separating the said tubes to form an I uninterrupted evenly spaced tortuous passage extended lengthwise between the said tubes; an inlet distributing chamber connected with said tubes, said chamber being provided with a series of perforations opening into said passage for controlling the delivery of gas thereto; a delivery chamber mounted upon said tubes to receive the gases from said chamber; and a plurallty of valve controlled outlets connected with said delivery chamber to control the passage of gas from said condenser. a

3. A condenser for gases, comprising a plurality of circumposed tubes, said tubes being annularly corrugated, the corrugations of one tube extending between the corrugations of another tube; an open center ring-shaped inlet distributing chamber opening into said passage; and means for separating said tubes to form an uninterrupted tortuous passage lengthwise between said tubes.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
